Prayer to the most holy Mary to obtain holy perseverance

Oh queen of heaven, I who once have been a
miserable slave of lucifer, now dedicate myself
to thee, as thy servant forever, and offer myself
to honor and serve thee for the whole life;
accept me, do not refuse me as I merit. Oh my
mother, I have placed in thee all my hopes, from
thee I hope all blessings. I thank and bless
God, who in his mercy has given me this confidence
in thee, which I consider as the great
earnest of my salvation. Ah, how have I fallen
in my past life, I a miserable sinner, because I
have not had recourse to thee! Now I hope
to be pardoned through the merits of Jesus
Christ, and through thy prayers. But I may
again lose the divine grace; the danger is not
over; my enemies do not sleep. How many new
temptations remain for me to conquer! Ah, my
most sweet Lady, protect me, and do not permit
me again to be their slave; help me always. I
know that thou wilt help me, and with thy help
I shall conquer, if I recommend myself to thee
but this I fear, that in occasions of falling into
sin, I may neglect to call on thee, and thus may
be lost. This grace I ask of thee, obtain for me
that in the assaults of hell, I may always have
recourse to thee, saying: Mary, aid me. My
good mother, do not permit me to lose my God.
